The DOM UI Events spec guidelines (see
http://www.w3.org/TR/DOM-Level-3-Events/#keys-guidelines) don't allow for
"non-standard" |key| values - do we need to file a spec bug to support this?

[kpschoedel, 2015/06/08 22:30:02]

Yes, that section seems clear. (The |key| document
http://www.w3.org/TR/DOM-Level-3-Events-key/ alone seems ambiguous, though, with
phrases “… implementations must support, at a minimum …” and “… key values not
included here, which have become common since the publication of this
specification.”)

That does seem ambiguous - perhaps garykac@ can clarify & update the wording in
whichever of the two docs is correct wrt what the working group agreed.
